iii said l' aiming;

pawl to pass on its forward movement, relative to the finger operating,but said fingers are made stiii' enough to throw the pawl on its returnmovement without thereby being bent. A convenient backing :tor the ngersis provided by beveling the edges of the perforation 24 of the slide,substantially as indicated at 2S.

Fig. 5 is added in order to show how a handle 29 maybe mounted directlyon the slide, when convenient, thereby eliminating the cord 10 and thepulley mechanism 11.

In Fig. 2 is shown a double construction, which differs from the aboveonl 7 in the manner of fastening' the cleaning bar 32 on the rods 14 ofthe mechanisms, which in this case are made right and left, by means ofa modified extension tube 33. Pulleys 34, 35 are provided for thepurpose of guiding both pulling cords to the `operating handle 36.

.The cleaning device herein described is readily operated by the personoperating the vehicle, and he does not have to stop the vehicle orotherwise interfere with its ruiming. It is also seen that the cleaningbar operates on the down-stroke, pulling the rubber insert over theglass pane, and that on returning the said bar swings entirely out ofthe way of said` glass, therelry releasing' the mechanism, which thenreadily is retracted by the spring, as described. The means of attachingthe device to the window sash may, of course, be varied to suitconditions, Jr, if the sash is hollow, the device may be built rightinto the sash.

-" lVe claim:

l. In a device of the character described, a tubular frame comprising avertical por tion and a horizontal portion, a slide mount ed tc move insaid vertical portion, a hori- Zontal cleaning frame rotatably fixed insaid slide, a spring-held spindle in said horizontal portion andconnected to draw said slide upward, manual means for drawing the slidedownward, and resilient fingers on said vertical portion coperating withsaid cleaning frame for the purpose of directing the frame relative tothe g1ass.

'2. In a device of the character described, a horizontal support to bemounted on a saslrframe, means for yieldingly retaining the support atthe top of said frame, means for drawing said Asupport; downwardly, adetachable cleaning bar on said support, means on the support tolongitudinally adjust the cleaning bar and means to press the cleaningbar against the adjacent window glass on the down stroke and away fromsaid glass on the up stroke.

3. In a devicel of the character described, a vertical tube, a slidemovable in said tube, a horizontal rod fixed to' oscillate in said slidyand extending` through a slot the length of the tube7 a pawl on said rodwithin said 'slide and presenting its apex toward an open-f ing in theslide, resilient fingers fixed at the j top and bottom of the tube, acleaning frame detachu bly fixed on said rod,means for draw@ ing saidslide downward through the tube, a retracting spring for returning theslide,

the said fingers operating on reversing the' movement of the slide toshift the said cleaning frame against the adjacent window pane on thedownstroke and away from the pane on the upstroke..

In testimony whereof, We have hereunto aiiixed our signatures.
